Question

I am using a stream reader to read a text file and then using Linq for retrieving the information

String fileContent = prodFileStreamReader.ReadToEnd();

 var mydata = from con in fileContent.Split('$').Select(x => x.Trim())
                    where !String.IsNullOrEmpty(con)
                    select new BaseSegment
                    {
                      dataID = con.Substring(0, con.IndexOf('#')),
                      dataElms = con.Split('#').ToArray(),
                      dataCon = con,
           lineNumber = 
                    };

I would also like to get the line number. I tried using Index but I was not able to. How to query to get the index and assign it to lineNumber?

Try using the select that projects index into each item, as given in this msdn article: http://msdn.microsoft.com/en-us/library/bb534869.aspx

In your case something like this (not tested):

var mydata = fileContent.Split('$')
             .Select(x => x.Trim())
             .Where(con => !String.IsNullOrEmpty(con))
             .Select((con, index) => new
                             {
                                 dataID = con.Substring(0, con.IndexOf('#')),
                                 dataElms = con.Split('#').ToArray(),
                                 dataCon = con,
                                 lineNumber = index
                             });
